结论大鼠第三脑室、中脑水管及中缝背核内存在多巴胺能触液神经元，其在脑-脑脊液之间的信息传递中有着重要的作用。
Conclusion the dopaminergic CSF-CNs located in the third ventricle and mesencephalic aqueduct might play an important role in transmitting information between brain and cerebrospinal fluid of the rat.
目的观察大鼠第三脑室、中脑水管及中缝背核内多巴胺能触液神经元的分布情况。
Objective To observe the distribution of dopaminergic cerebrospinal fluid-contacting neurons (CSF-CNs) in the third ventricle and the mesencephalic aqueduct of rat.
内侧径路经间脑室周、中脑中央灰质、第四脑室底、孤束核—迷走背核复合体、延髓与脊髓中央管周下行。
The other bundle from PVN, the medial, descends through diencephalic periventricular gray, periaqueductal gray, floor of ventricle IV, SVC and medullary-spinal central gray.
结果：NOS阳性触液神经元主要见于中脑水管和第三脑室（3V）。
Results:The NOS positive CSF contacting neurons were mainly at the cerebral aqueduct and the third ventricle(3V).
